The 290 flywheel or flex plate will be my biggest expense in getting this motor in. 


I can ship a rebuildable 360 to you for $250.00 plus shipping. Sorry, no trades. LOL!
You could find a early 6cyl or a 343  flywheel or flex plate and have it match balanced to your existing 290 flex plate if you want to use the 290.

MU 1675-1D zoom clutch for a Jeep works on the swap. Has disc, plate and bearing. It also comes with pilot bushings and alignment tool. You'll need to replace the bushing for the correct ID.
For the T4 or T5 make sure that you have the Jeep bearing retainer.  Speedo cable is the same as your old trans.

My biggest/most expensive problem is I don't have a 290 flex plate or flywheel at all.  I could pick up a neutral balance fly wheel or flex plate but I don't have a 290 to match balance it with.  

I am assuming the machine shop would need a 290 plate/wheel to match the balance with another.  is it possible to get the the balance specs to weight one without a using a master?

Not a lot of options. You can toss about a hundred at a used 290 flywheel. You can toss 400 towards a new billet piece that has no projected build date ( been there). Or just scrap the idea.

Maybe make it easier. What are you planning on a budget for the whole swap? Everything from bellhousing to correct length driveshaft and yoke.
Maybe it's feasible maybe it isn't.

I will have to have the drive shaft done either way, I have the drive shaft and both yolks.  The cost is about the same if I go 904 or T-4.  I would prefer the T-4 so I would have another gear.  

My wife says I'm cheap, I prefer frugal; I have hard time dropping $400.00 on a flywheel.  I haven't found any of the $100.00 used flywheels.

I have learned to think in terms of what a $$$ part does to the overall project -- a single pricey part that solves a problem in one shot is a bargain. WHen I arbitrarily assign a price to a part based on past experience, it often hangs me up thinking-wise. A pair of new expensive OEM brake calipers is still cheaper than buying a whole disc conversion kit, never mind all the work and balancing etc. That $400 flywheel is a bargain if it gets you precisely what you want in one shot.
